Chordbot

Chordbot is a songwriting app for creating and playing chord progressions in different musical styles, and for generating backing tracks. It is available on Android and iOS. The library offers more than 60 chord types in all inversions, alongside more than 70 comping-style presets; users can also combine over 400 instrument tracks to create styles. An automatic or manual inversion selector helps manage chord transitions, and repeatable song sections can have their own arrangements. Song-O-Matic can generate chord progressions. Songs can be exported as MIDI for DAW editing or as WAV files for sharing. Song files use JSON and can be shared through file-sharing apps, but only JSON files can be imported back into Chordbot. The free Chordbot Lite plan disables saving and exporting. Chordbot Pro costs $4.99, paid once and enables both. The maker grants a perpetual, non-exclusive, royalty-free license for creations used in commercial recordings and performances.

Chordbot offers progression generation, arrangement options, and audio or MIDI exports in its paid version. The free Lite plan does not save or export, and imports back into the app are limited to JSON song files.

Chordbot may suit songwriters who want to explore chord progressions, arrange backing tracks, or create material for guitar solos. It may also fit users who want MIDI or WAV exports, provided they choose Pro.

Overview

Chordbot is a mobile tool for building chord progressions and arranging backing tracks in different styles. It is best for songwriters who want to sketch harmony and accompaniment on Android or iOS. Its distinctive strength is the depth of its chord and comping choices; it is a poor fit for anyone who needs lyrics, melody writing, or a project they can freely round-trip through audio files.

Key features

The library contains more than 60 chord types in all inversions, and an automatic or manual inversion selector helps smooth changes between chords. That combination gives harmony-minded writers more control over the motion of a progression than a basic chord picker, without extending into melody tools.

More than 70 comping presets offer quick arrangement starting points. Users can also combine over 400 instrument tracks to create styles, then build repeatable song sections with different comping styles or arrangements. Song-O-Matic can generate progressions when a starting idea is elusive. Together, these tools make Chordbot a focused backing-track sketchpad, rather than a broad songwriting suite.

Demo recording is supported, and songs can be exported as MIDI for further work in a DAW or as WAV for sharing. The import boundary is important: only JSON song files can come back into Chordbot, not MIDI or WAV exports. JSON projects can be shared through file-sharing apps such as email, iCloud Files, Google Drive, Dropbox, and OneDrive. The maker grants a perpetual, non-exclusive, royalty-free license to use creations in commercial recordings and performances.

Pricing

Chordbot Lite is free (free), but saving and exporting are disabled. That makes it suitable for trying the progression and arrangement workflow, not for keeping or delivering finished work.

Chordbot Pro costs $4.99, paid once. It enables saving and exporting, so it is the practical choice for users who want to preserve ideas or move MIDI and WAV output into other workflows. There is no free trial. Licenses cannot practically transfer between Google Play and Apple's App Store, so switching platforms means buying another copy.

Platforms

Chordbot is available on Android and iOS. Its mobile focus suits writing away from a computer, while MIDI export provides a handoff to a DAW when more editing is needed. The app supports collaboration and file sharing, but its own project import is limited to JSON.

Who it's for

Choose Chordbot if you want to explore chord combinations, make backing tracks for guitar solos, or try different arrangements from a phone or tablet. It is less suitable if your process depends on lyric or melody tools, or on importing an exported audio or MIDI file back into the same project.

Pros and cons

Pros

• More than 60 chord types, all inversions, and selectable inversion handling give progression writers meaningful harmonic options.
• Over 70 presets, more than 400 instrument tracks, and section-specific arrangements support varied backing-track sketches.
• MIDI and WAV export, plus commercial-use permission, make saved work useful beyond the app.

Cons

• The free Lite plan cannot save or export, sharply limiting it as a continuing workspace.
• MIDI and WAV files cannot be imported back; only JSON song files can re-enter Chordbot.
• There are no lyric or melody tools, so writers seeking a fuller song-creation toolkit will need something else.
• A license bought on one mobile platform does not practically transfer to the other.

Alternatives

For a broader set of songwriting software, compare tools by the parts of the process you need beyond chord-based backing tracks.

Pick Suno instead if you want an Android or iOS freemium option with a free plan offering 50 credits per day and eight minutes of audio upload; its Pro plan is $8 a month, with taxes calculated at checkout.

Topline is a free Android and iOS alternative for readers who want a free app and do not need Chordbot's paid saving and export workflow.

Choose Song Cage if you want a freemium songwriting option across mobile, desktop, and web, with a free web app for one song and tools for chord palettes, voicings, modulation, words, playback, and audio recording.

Songkeeper Studio suits writers who want a free starting tier capped at five songs, two drafts and two recordings per song, with writing tools; its Pro plan is $0.99 a month.

Pick SONGTAKE if you need an iOS or macOS option centered on production features such as 1TB storage, 16 tracks per song, offline mode, and band storage sharing; Studio Access is $7.49 a month.

Songwriter's Pad is another option for writers interested in AI lyric generation, with a free tier limited to 750 AI word tokens and three songs.

Consider Songzap if you want an iOS or macOS freemium app whose free tier includes four-track audio recording, audio bounce and import, an arrangement editor, and an AI Beats Designer.

Suonote is a free iOS alternative.

Verdict

Chordbot is a strong fit for mobile songwriters who want to shape chord progressions into arranged backing tracks, especially when inversion control and varied comping styles matter. Its low one-time Pro price unlocks the essential ability to save and export, but the free version is only a trial of the workflow, and the JSON-only import rule makes it less compelling for users who expect an editable audio or MIDI project to travel back into the app.
